Abstract :
Two distributed RC filters (a low-pass and a bandpass) that use MOS transistors as distributed RC lines are presented. A scheme for compensating for nonlinearities in the MOSFET is used. Simulation results for a 2-μm CMOS p-well process (MOSIS) are presented. High programmability is expected from two tuning points: the gain of the voltage amplifier to control the Q of the filters, and the DC bias of the MOSFETs to change ω0. SPICE simulation results are presented
